The Problem

The Problem Every Restoration Contractor Knows

Adjusters Slash Equipment Charges

Your dehumidifiers and air movers get cut without technical justification. You lose thousands per claim — with no way to fight back.

Drying Time Gets Questioned

Insurance companies challenge equipment duration, ignoring the physics of moisture removal and psychrometric science.

You Don't Have Time to Fight

Writing detailed technical rebuttals takes hours you don't have. Meanwhile, the adjuster moves on to the next denial.

What We Do

Technical Justification Reports That Adjusters Can't Ignore

We don't guess. We calculate. Every TJR is built on IICRC S500/S520/S800 standards and psychrometric science.

Room-by-Room Psychrometric Analysis

Cubic footage calculations, LGR dehumidifier sizing formulas, air mover deployment ratios — all per IICRC S500. Every room, every factor, documented.

Equipment Sizing Verification

We verify every dehumidifier, air mover, and air scrubber against the IICRC S500 Factor Chart. Math, not opinion. AHAM ratings confirmed.
